ABSTRACT:
A security system includes a central console, one or more locks, one or more console coded programmers to transport data in a secure manner between the central console and one or more of the locks and one or more enabling programmers to enable the lock to operate upon insertion of a special key into the lock. The central console encodes combination codes from its memory which correspond to combination codes stored in a memory level of one or more locks in the system. The encoding results in a first modifier code which is combined with other information to form a programmer data word. The central console processor next scrambles and transfers the resultant coded data word to a console coded programmer. The console coded programmer stores the coded data word in its memory until a communication link is established between a lock and the programmer. Thereafter, the console coded programmer first unscrambles the coded data word and then further encodes the first modifier code to obtain a second modifier code. The resultant modified data word is transferred to the lock which is programmed to first decode the second modifier code to obtain the first modifier code and then to decode the first modifier code to obtain the combination code to be used in the lock.
